Purpose: Korean adolescents have severe nighttime sleep deprivation and daytime sleepiness because of their competitive educational environment. However, daytime sleep patterns and sleepiness have never been studied using age-specific methods, such as the pediatric daytime sleepiness scale (PDSS). We surveyed the daytime sleepiness of Korean adolescents using a Korean translation of the PDSS. Methods: We distributed the 27-item questionnaire, including the PDSS and questions related to sleep pattern, sleep satisfaction, and emotional state, to 3,370 students in grades 5-12. Results: The amount of nighttime sleep decreased significantly with increasing age. During weekday nights, $5-6^{th}$ graders slept for $7.95{\pm}1.05h$, $7-9^{th}$ graders for $7.57{\pm}1.05h$, and $10-12^{th}$ graders for $5.78{\pm}1.13h$. However, the total amounts of combined daytime and nighttime sleep during weekdays were somewhat greater, $8.15{\pm}1.12h$ for $5-6^{th}$ graders, $8.17{\pm}1.20h$ for $7-9^{th}$ graders, and $6.87{\pm}1.40h$ for $10-12^{th}$ graders. PDSS scores increased with age, $11.89{\pm}5.56$ for $5-6^{th}$ graders, $16.57{\pm}5.57$ for $7-9^{th}$ graders, and $17.71{\pm}5.24$ for $10-12^{th}$ graders. Higher PDSS scores were positively correlated with poor school performance and emotional instability. Conclusion: Korean teenagers sleep to an unusual extent during the day because of nighttime sleep deprivation. This negatively affects school performance and emotional stability. A Korean translation of the PDSS was effective in evaluating the severity of daytime sleepiness and assessing the emotional state and school performance of Korean teenagers.

This study examined (1) whether romantic partners' or close friends' acceptance-rejection perceived by college students is related to their psychological adjustment indicated by hostility/aggression, dependency, negative self-esteem, negative self-competence, emotional unresponsiveness, emotional instability, and negative world view; (2) whether parents' behavioral control in childhood and romantic partners' or close friends' behavioral control perceived by college students are related to their psychological adjustment; (3) how parents' behavioral control and acceptance-rejection in childhood perceived by college students are related with each other; and (4) how romantic partners' or close friends' behavioral control and acceptance-rejection perceived by college students are related with each other. The subjects were 163 college students enrolled in universities located in Seoul or Kyungki-do in Korea. The results indicated that college students' perceptions of their romantic partners' or close friends' acceptance-rejection are related to their psychological adjustment, that college students' perceptions of their parents' behavioral control and romantic partners' or close friends' behavioral control are related to their psychological adjustment, and that college students' perceptions of parents' behavioral control are related to their perceptions of parents' hostility/aggression, indifference, and rejection and the results were the same for the romantic partners' or close friends' behavioral control and acceptance-rejection.

The emotion recognition system in commercial environments such as call-center undergoes severe system performance degradation and instability due to the speech characteristic differences between the system training database and the input speech of unspecified customers. In order to alleviate these problems, this paper extends traditional method of emotion recognition of neutral/anger into two-step hierarchical structure by using emotional characteristic changes and differences of male and female. The experimental results indicate that the proposed method provides very stable and successful emotional classification performance about 25% over the traditional method of emotion recognition.

In this research, one's ability to perform activities of daily living, body pain, and emotional states of elders who live alone and elders who live with others were compared to investigate which factors affect senior's health state. The data was collected from 88 seniors and analyzed for the comparison. Compared to seniors who live with others, elders who live alone had lower activity of daily livings, stronger body pain, and instability in emotional states. These 3 aspects showed a statistical significance of correlation. As a result of further analysis, not only residential types(living alone or living with others), but also life pattern(indoor or outdoor) is affected on the results. It is expected that the results of this research could be used as basic data for physiological index to evaluate senior's health state and care service for seniors who live alone.

Purposes: The purpose of this study was to analyze the association between discrimination experience and quality of life among non-regular workers in hospitals. Methodology: The data was collected from 292 employees of 7 university hospitals using a standardized questionnaire. In research methodology, the data was analyzed with descriptive statistics, t-test, ANOVA, pearson's correlation, multiple regression analysis. Findings: In case of non-regular workers, inequality of distribution, position unfairness, employment instability, number of discrimination experiences were found to have a negative(-) effect on quality of life. Religion, income in general characteristics had a significant positive(+) effect on quality of life. And the discrimination of non-regular woman workers was higher and the quality of life was lower than that of men. Practical Implications: These results showed that hospitals needed active efforts to create non-regular woman-friendly work environment. In addition, active religious activities gave emotional stability and positive effect to no-regular workers.

A 64-year-old man with TBI was admitted to our institute. In following days, he showed unusual behavior of agitation, restlessness, emotional instability and inattention. Post-traumatic delirium was tentatively diagnosed, and donepezil was given for his cognitive dysfunction. Although there was partial relief of agitation, he sustained back pain despite medication. Lumbar magnetic resonance image revealed SDH along the whole lumbar spine, and surgical drainage was followed. Postoperatively, his agitation disappeared and further medication was discontinued. We report a unique case of post-traumatic delirium in a patient with concomitant TBI and spinal subdural hemorrhage (SDH) that resolved with operative drainage of spinal hemorrhage.

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by abnormalities in social communication/interaction and restrictive, repetitive patterns of behavior. ASD is a relatively common psychiatric disorder, with a prevalence of approximately 1.7% in children. Although many children and adolescents with ASD visit the hospital for medical help for emotional and behavioral problems such as mood instability and self-harming behavior, there are also many visits for sleep disturbances such as insomnia and sleep resistance. Sleep disturbances are likely to increase fatigue and daytime sleepiness, impaired concentration, negatively impact on daytime functioning, and pose challenges in controlling anger and aggressive behavior. Sleep disturbance in children and adolescents with ASD negatively affects the quality of life, nothing to say the quality of life of their families and school members. In this review, sleep disturbances that are common in children and adolescents with ASD and adolescents are presented. The developmental and behavioral impacts of sleep disturbances in ASD were also considered. Finally, non-pharmacological and pharmacological treatments for sleep disturbances in children and adolescents with ASD and adolescents are reviewed.

The foster care system is a social welfare service that supplements the functions of the family while enabling children, who cannot receive proper care from their biological parents, to receive the necessary protection under the plan within the prescribed period of time within a substitute or foster family. A large part of the emotional instability experienced by foster care children is interpersonal maladjustment. Low self-esteem leads to difficulty in forming social relationships due to negative interpersonal relationships. Thus, the purpose of this study is to investigate the effects of traditional dance programs on the foster children who live in Daejeon Metropolitan City. A comparison between the pre- and post-interpersonal scores showed that the scores were improved after the traditional dance program, and the children's intimacy formation and communication were also improved. The participants were less active at the beginning of the program, but became more interested and more active toward the middle of the program. The majority of the participants increased their degree of communication with the formation of intimacy toward the middle of the program, and their self-confidence improved in terms of their peer relationships. The purpose of this study was to investigate the effects of traditional dancing on the development of interpersonal relationships. In a subsequent study, a traditional dancing program consisting of various contents will be applied over a long period of time, which should provide them with the opportunity to improve their interpersonal skills. In addition, it is necessary to provide educational opportunities for helping foster children reduce their emotional instability with systemic and diverse traditional dance programs.

This study examined the effects of group social support on the reduction of burden and increase in well-being of mothers of developmentally delayed children. The research used a one group pre-pose experimental design. The independent variable in the experiment was group social support. Two series of 4-weekly meetings for group social support were conducted by the researcher with the intention of developing a self-help group. The dependent variables were burden and well-being. Well-being was operationalized as physical symptoms and quality of life. Thirty mothers of developmentally delayed infants from the rehabilitation center of a medical center participated in the study. Data were collected by interviews and a self-administered questionnaire. The mean age of the subjects was 29.9 years. Changes of the dependent variables between pre and post tests were compared using the t-test. Even though there was a slight improvement in the scores for the dependent variables, they were not statistically significant. The items, "I resent my baby". "I feel angry about my interactions with my baby", "I feel guilty in my relationship with my baby" showed a significant decrease in burden score and were statistically significant. Symptoms of loneliness, constipation, anxiety, restlessness were less and feeling of happiness was greater after participation in the group social support, than on the pretest. The mothers showed emotional instability and frustrations during the group sessions but their reactions in general were positive. Emotional support, stress management and information provided were identified as the most valuable content of the sessions. However, participation was not active due to the mother's denial, delayed acceptance and /or avoidance of their infants' problems. It can be seen that group social support for the mothers with developmentally delayed children should be provided after infancy when the mothers have time to accept their children's conditions and are ready to receive support. The use of comprehensive instruments which measure burden in both families and mothers needs to be developed for future research.
